Application filed June 27. 1919. Serial No. 307,183.

To all who! it may r-on -ern lie it known that I. Enwlx ll. Samoa, :1 eitizen ot the l'uited States. residing at ('lei eland. in the county of (uyahoga and State of Ohio. have invented a certain new and useful [In iroveluent in 'I'raek-llelt l'nits. of which t in following is a full. elear,

and exact description.

ine:4.-4. fie-5.6+; on Fig. l." r'itraek. belt: unit" E eomposed the shoe 10, on! the two link side operation-s20. 2f).

the il .plate haw-m a downturned front end 12 wliieh series as 'a gro|i1 ul' engaging erronser. This shoe also has through it numerous slots 13. the purpose of whieh will he snl isequently explained.

.lnd eaeh has one or more dowmrardlv extended tongues whieh'go through a slot in the shoe and has its projecting lower end upset against the lower surfuee of said shoe. in the speeitio oonstruetion shown earh of the link sides is made of a single piece of sheet metal whieh is so-eut and bent as to produee a horizontal top nielnher eonlpri-;-

. 0 I u mg a wule nuddle portion ll and two disalined narrow end extensions 22, 23. whieh n'o'eet res )eetirelr haekward and forward l from said middle portion,-.-said extensions living so plat-ed that the outer edge of the forward extension is a substantial eontinuation of the outer edge of the middle portion. and the inner edge of the rearward extension is a substantial eontinuation of the innor edge of tho iniddle portion. liaeh of these link sides also ineludes downwardly turned vertical flanges whieh are integral in glii'ated in Fig. '1.

i'ention is embodied: Fig, 2is a1 of the link sii'les n -jlie planes with the top member. One of these flan es 24 extends down an] along the inner e go of the wide top portion 21, and downward also along the inner-edge of the narrow rear extension 22.

Another flange 25 extends downward along the outer edge of the wide middle ortion 21. and also along the outer edge of the narrow forward extension 23. The flange 26 extends dowmrard along the outer edge of -the narrow rearward extension.22 and the flange 27 extends downward along the inner edge of-the narrow forward extension 23. Preferably-a considerable part of the flanges :34. 25. that is, the part thereof which ex- .tends down from the wide middle top portitiil il, have their lower iifes therefore e,.\ short distance, j lgtlltn the wid n ll iitornable itl't ie'i the narrow frontektension'235.1118 also 1; 1e 't'o'rni ot' a narrow inverted 'flat U,'which, lmwei'er. is not alined withthebox-respondin; parts of the rearward extension. The rerliral transverse sertion on line of lfig. I. through the middle part of the link side; also takes 'the form of an. inverted flat: U \Vllilll on its upper end is Isubstantially twiee as wide astho upper endsof the other two 'U-shaped soetions: and'tluf side flanges do not extend down nearlyas far.

'()u the lower edges of Ithe'long downuuirdlr extended side. flanges, thetongtles 2!) are (owned. 'lhese projeet through the in the shoe; and their n'O eeting lower surslots l-t lower ends are upset against the lave of the shoe. thereby securely these link sides to the shoe and holding them.

tirlnly down upon-the same.

lioth link sides are similarly shaped and l so fastening slightly greater than the distance between the outer surfaces of the two outside flanges 26 of the rearward extensions. Therefore the rear extensions of the two link sides of one link may go between the forward extensions of the link sides of the next adjacent link; and may be pivoted thereto by any suitable means,-the overlapping portions of the flanges 24, 25, 26, 27, being perforated for the reception of the pivoting devices.

Havin described myinventiomlclaim 1. A t ree piece pressed metal'track belt.

link comprising, in combination, a shoe having longitudinal slots near its side edges, and two link side members, each having on its lower edge 'a tongue which goes through one of said slots, and has its lower projecting end upset against the lower surface of sald shoe.

2. A link belt unit comprising a shoe having slots through it, and link sides, each of which has a fiat top member and side flanges which are turned down from said top mem' her, said flanges having tongues on their lower edges which pass through the slots in the shoe and are upset against the lower face of said shoe.

3. A link belt unit eompi'isin a shoe having slots, and two link sides eae 1 comprising a wide niiddle top part having downwardly extended flanges along both side edges and two narrow end portions each of which has (lOWlDVill'tlhY turning flanges along the side edges,-said downturned flanges being formed with tongues which pass through the slots in the shoe and are upset against the lower face of said shoe.

In testimo ny whereof, I hereunto atlix my signature.
